BOX FOR PACKING MANTLES FOB INGANDESGENT GAS-LIGHTING.

reoozoo.

To all whom it may concern:

Be it known that I, HANS SOHMALLAND, merchant, a subject of the German Emperor, residing at Schutzenstrasse 2, Steg litz, near Berlin, in the German Empire, have invented certain new and useful Improvements in Boxes for Packing Mantles for Incandescent Gas-Lighting, (for which I have applied for a patent in Germany, and which application is dated November 9, 1907, No. I). 19.214: III/81, and in England, No. 27,710 of 1907, dated December 16,1907,) of which the following is a specification.

Mantles for incandescent gas lighting, particularly those used for inverted burners, are frequently sent out by the manufacturer attached to a mantle ring. The usual method of packing such mantles is to suspend them by the ring, or the usual tangs or projections thereof in the upper part of a box of suitable shape and to retain them in place by covering them with a piece of card board or the like, with or without some loose material (cotton wool say) held down by the lid of the box.

According to the present invention how ever the box is so constructed that, instead of being suspended, the mantle ring rests on the bottom of the box. By this construction, the mantle, is carried securely without requiring any loose packing, (such as cotton wool), can be inspected without removal from the box, so that faults, if any, can readily be seen, and the mantle can easily be placed into and removed from the box.

The said invention is illustrated in the accompanying drawing in which is shown, by way of example, a box with a mantle therein, one side of the box being broken away to show the arrangement of the interior.

It is an essential feature of this invention that the box has a false bottom, out out for the reception of the mantle, or a flange surrounding the interior near the bottom, so that the tangs or projections on the mantle ring, or some of them, slip in between the bottom and the false bottom (or flange) and are clipped by the latter.

In the drawings a is the false bottom and b the bottom of the box. The tangs c, 0, on the mantle ring engage under the false bottom and are clipped thereby; the tang cl nearest the falling front of the box is Specification of Letters Patent.

held by a slip piece 6 that is slipped into position after the mantle is in place; the ends 6, e, of the loose piece being retained by the corresponding portions of the false bottom a. The falling front of the box is marked 2'; its end ,2" slips into the fold or recess f when the box is closed. WVhen the box is closed the front 2' prevents displacement of the loose piece 6.

* As shown in the drawings, the false bottom a is provided with a slot 8 concluding with a semicircular margin which makes the box universal in use for mantles of the type having any number of tangs for attachment thereof to the burner, that is, the box as shown, is applicable for use with mantles having three tangs, or four or any number of tangs, the slot at its opening being of a width substantially that of the diameter of the mantle ring at the juncture of the tangs therewith, and the inner semicircular margin holds the mantle rigidly in place.

The slip piece 6 is provided with two spaced apart projections p which, when the slip piece is in place, project at either side of one of the tangs and prevents movement of the mantle ring ciroumferentially.

Although the box is shown containing a mantle the ring of which has three tangs, it will readily be seen that a mantle having four or five tangs could be supported in the box and that the slip piece would engage one of the tangs to prevent movement as described.

Instead of having three fixed sides and a falling front, the box may have two or more falling sides and these may be held together by a lid or cover, or otherwise.

A box embodying this invention may conveniently be made of card board, straw board or paste board; the pieces of which it consists being glued or cemented together, or united by wire-staples say. The box may however be made of metal or partly of metal, and so forth. Its shape may also vary considerably.

Claim.

A box for containing gas light mantles having ringed bases with a plurality of tangs projecting therefrom, said box including in combination, a wall, a retaining member carried by the box and spaced apart adjacent to said wall, said retaining member having a slot concluding with a semicircular margin for the reception of the mantle ring with the tangs thereof confined between the retaining member and said wall, and a slip piece provided with spaced apart projections adapted to engage the sides of one of the tangs of the mantle ring to prevent circumferential movement of the latter, the slip piece being adapted for confinement between said retaining member and said 10 wall.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses this 26th day of October, 1908.
